Walleye
Sander vitreusAlso known as Walleyed Pike, Yellow Pike, Yellow Pikeperch, Yellow Pickerel
Walleyes are apex freshwater predators named for their milky, reflective eyes, which feature a light-gathering tapetum lucidum layer that enables superb vision in dim or turbid water. They patrol deep lakes and large river systems, hunting primarily during twilight and nighttime when their acute sight gives them a distinct edge over disoriented prey. In early spring, adults migrate to rocky shallows and tributary rapids to broadcast millions of eggs over clean gravel.
